Application March 21, 1935, Serial No. 12,176

3 Claims. (01. 240-54) This invention relates to portable incandescenelectric lamps.

Principal objects of the invention are:

To provide a mounting for a lamp of the type specified, which is ofimproved and simplified construction, effective for its designedpurpose, and relatively inexpensive to manufacture;

To provide a mounting for such lamps, all parts of which are made of, orencased in, suitable, resilient, insulating material, whereby a personhandling said lamp in the manner contemplated, will be effectuallyprotected from shock in case of grounding of metallic parts of the lamp;and

To provide a combination hook and handle for such lamps, which isreinforced so as to im-- part requisite strength thereto, by means of ametal rod the inner end of which is embedded in the wall of the holderfor the lamp socket, and the outer portion of which forms a core for thecombination hook and handle of the lamp. i

In accordance with the invention, I attain the objects thereof by theuse of a mounting member comprising a holder provided with a usualrecess shaped and proportioned to receive and hold the lamp socket, aboss provided with a hole or opening which communicates with the innerend of the recess for the lamp socket, through which the electricalconnections tothe lamp socket extend, and a combined hook and handle,which is reinforced and strengthened by a core member, preferably ametallic rod, all forming a unitary structure, which conveniently andeconomically can be cast from suitable insulating material.

In the accompanying drawing, in which the invention is fullyillustrated,

Figure 1 is a central, longitudinal, sectional view, of a mountingmember embodying my invention and improvements, substantially on theline l--l of Fig. 2;

Figure 2 is a bottom plan view of'the holder for the lamp socket and thecombination suspension hook and handle, with detachable parts of thelamp removed; and

Figure 3 is a sectional view of the combination hook and handle portionof the mounting member on the line 3-3 of Fig. 1.

Excepting as regards features hereinafter particularly described andpointed out, a lamp embodying my invention and improvements may be ofany usual or approved construction and will readily be understood bypersons familiar with such lamps from an examination of the drawing,without a description thereof in detail.

Referring now to the drawing, a lamp embodying my invention andimprovements, for conmanner.

venient reference designated as a whole A, comprises a mounting memberdesignated as a whole B, which includes a holder b provided with a usualrecess l adapted to receive the lamp socket c, a boss at provided with ahole 2 which communicates with the inner end of the recess l in theholder, through which the electrical conductors connected to the lampsocket c extend, and which, as shown, extends at an angle ofapproximately 45 degrees to the longitudinal axis of the lamp. As shown,also, said holder b also comprises a combination suspension hook andhandle designated as a whole e, which, like other parts of said mountingis made of suitable resilient, insulating material, and is reinforcedand strengthened by a metal rod 3, the inner end 4 of which is firmlyembedded in the wall of the holder in and the rest of which forms a corefor said combination hook and handle e, as clearly shown in Fig. 1 ofthe drawing, the size and char- 20 actor of said rod or core 3 beingsufiicientto impart requisite strength and stiffness to the handle,while the covering of said core will operate, in an obvious manner, toprevent shock to a person handling said lamp. 2 In accordance with theinvention, the holder 1), the boss (1, and the combination suspensionhook and handle e, excepting only the reinforcing rod 3 thereof, aremade of suitable, resilient insulating material, preferably rubbervulcanized to a degree sufiicient to impart contemplated rigiditythereto, and-again excepting the reinforcing rod 3-are all cast in oneoperation in a suitable mold to form a single unitary structure.

In what I now consider a preferable'arrange- 35 ment, the shank of thecombination hook and handle e, is shaped to extend over the top of theholder b at an angle of about 45 degrees to the vertical axis of thelamp, and then turns reversely on a relatively flat, substantiallysymmetrical 40 curve, as shown, the relation preferably being such thatthe high point thereof will be substantially in line with the verticalaxis of the lamp.

As shown, a light bulb 5 is secured in the lamp socket c, and a lampguard or cage 6 is at- 45 tached to the mounting member B, which isprovided with an exterior groove 1 in which the ends of the wiresforming said cage are secured by means of a split clamping ring 9, allin a usual I claim: 1. A mounting for a portable incandescent electriclamp, made of suitable resilient insulating material, comprising aholder provided with a recess shaped and proportioned to receive a lamp5;

socket, having electrical contacts and means for making electricalconnections thereto, a boss pro.- vided with a hole which communicateswith the recess in said holder, for the passage of the electricconductors connected to the lamp socket, and a combined suspension hookand handle comprising a metallic core, the inner end of which isembedded in the wall of the holder and boss por tions of said mountingmember, and the portion of which beyond said boss is encased ininsulating material.

2. The mounting specified in claim 1, in which parts made of insulatingmaterial form an integral structure.

3. The mounting specified in claim 1, in which the hollow boss ispositioned at the closed side of the combination suspension hook andhandle, the relation being such that the shank of the suspension hookand handle extends over the closed end of the holder member and thenreversely to form an open-sided hook proportioned and arranged to beconveniently grasped and firmly held. 10
